Ability to add custom data to steps

Similar to attributes it would be nice we can add custom fields to steps and order them. For example this could be a way to add one or more URL fields (where the first in the list would be placed on the step card front. A link to the automation, a link to specific documentation or a link to whatever. Or the ability to create a field with ID's.

In a later iteration it would be nice if these would have multiple types (text, multiselect, singleselect, boolean) so you can make a tag system for example.
